On my system, this bypasses the attempt to use GBM, AND the fallback to Vulkan. There's no noticeable performance degradation for me when running Sigil in this way (but my hardware is pretty beefy).
I would recommend that anyone experiencing Sigil Preview problems/sluggishness on Linux (using Qt6.9.0+) at least try launching Sigil from a terminal with:
Code:
QT_QUICK_BACKEND=software sigil

Great!! With that command line Sigil 2.5.1 works flawlessly. Many thanks!! How can I add that command in my luncher? (to avoid run Sigil from CLI).
